TRENCH-SANDAL.

Original No. 1,276,964, dated August 27, 1918, Serial No. 197,829, filed October 22, 1917. Application for reissue led October 25', 1919. Serial No. 333,413.

`To all 'whom t 'may concern Be it known that I, CIIARLEsO. Ron, a citizen of the United States, residing lat Indianapolis, in the countyv of Marion and State of Indiana, have invented certain new and useful Improvements v1n Trench-Sandals, of which .the following is a specification.

`This invention relates to sandals to be worn with boots or shoes for trenchr work `in warfare and also in peaceful. pursuits 4vwith boots and shoes which will stand far from a perusal of the specification and greater and harder usage than leather;

which will give the wearer a rmer footingy ter equipoise of the body.

A furtherobject of the invention consists inthe provision of a sandal wherein `worn down spikes in the soles can beeasily and readily replaced, thereby prolonging"the life and utility of the sandal with a corresponding reduction in co'st'of replacement and maintenance. y

I accomplish the above obJects of the Vmvention, and such others as may appear claims, `by means of the construction illustrated in the accompanying drawing, forming a part hereof, in which- Figurejl is a side elevation of improved sandal showing the manner in which thesame is held in position on the wearers foot.

Referring to thedrawings, the sole 4and heel of the sandal are preferably composed.

of thin sheet steel .plates to sustain the y rough `'usage to which they are subjected. The sole 4of the sandal is composedof at least three sections-10, 11 and 12 Awhich have upstanding edges 10a, 11a, and 12a and are rhingedly secured togetherby means `of the hinge-connections 14 and 15. The upstanding edges just referred to `are slightly higher than vthe thickness of the heads 32 andare provided witlrthe inwardly turned hooks 44 whose purposewvill later` be de-` scribed. The hinge-connectionsA 14 and 15 1 extend transversely of the sandal and are located immediately beneath the ball of the foot where the greatest amount of bending occurs, and where the greatest amount of elasticity is-reoluired.l The free end of section 10v is bent downwardly at right angles to-provide an extension 16 which is slightly less 'than the height ofthe heel on, the shoe,

thereby providingv some latitude for the wearing down of the heel. ,Section 17 which forms the heelof the sandal is bent upwardly Aat one end to form a member 18 which member rests against extension 16, and member 18 is bent at right angles toV form a member 20 Awhi'chrests against the outer surface of the section 10 ofthe sole,

and members 16 :and 18, and, also, members 10 and 2O are rigidly secured together by means of suitable rivets, or by spotwelding.

This overlapping of sections 10 4and 17 reinforces the sandal at `its weakest pointwhere kthe sole and heelsections join. yHeel section 17 is provided along its side and rear portions with upstanding ears or members 45a to which the counter 21 is secured by means of 'suitable rivets, or by spot-welding. The heelsection 17 with its attached mem; bers 18, 20 andv 45a can be made by a single stamping operation. Section 12 of the sole is provided with a shoe tip 22 which may be riveted or welded thereto, to form a pocket for thetoe o the boot or shoe, and the heel section 17 is provided with a counter 21 for holding the boot or shoe in p osition in the sandal. Counter 21 is provided l on opposite sides with a slot 21a adapted vto receive a strap 23, the latter passing over the instep of the foot and serves to hold the sandal in operative position, on the boot or shoe. In addition to strap 23 provide a strap 24 which passes over the ball of the foot and engages the ears 26 formed integrally with section 11, and also with the ears 27 formed integrally with section 12 ofthe sole. The straps 23 and` 24 will be provided with ordinary buckles although any suitable attaching means may be used. Heel-section 17 and sole sections 10, 11 and 12 are provided with a plurality of apertures 30, and through these apertures I pass suitable tempered steel-spikes 31. Spikes or calks 31 are provided with thin flat heads y 32 soas to extend but a short distance above the surface of vsections 10, 11, 12 and 17. Spikes. 31 are easily removed from apertures 30 when-.worn down to where their utility is.' destroyed and may be easily replaced vby the-introduction of new spikes 31 into apertures 30, thereby making the sandals as effective as when new. rSpikes 31 are prevented from backing out or being displaced `from apertures 30 by means of suitable plates which are spaced -from the sections 10,l 11 and 12 a distance equal to the thickness ofthe heads 32 vand resttightly upon the flat heads of said spikes. To render the plates to be more easily removed and inserted .they are preferably divided along their' longitudinal centers into two members, in which the sections 35 and 36 are arranged within the heel portionof the sandal; members 37 and 38 being .arranged in section 10 of the isole' and members 39 and 40 in sec- Y tion 12 of the sole. Section 11.- is provided with a single member. 41,'tl1e'- latter being vnarrow and easily sprun -upward in 'the' *center to remove it, so t at this member may be made of a single piece o f material. The outer edges'of heel-members 35.and 36v v are held down into contact with the headsy of the underlying spikes 31 by means of the the adjacent edges of heel section 17 these ears being bent downwardly to form hooks bers'37, 38, 3.9, 40 and 41 are held down by the hooks44 whichrare formed byup-turning. the edges of saidv plates. The meeting edges of. members 35, 36, 37, 38,39 and 40 have coperating depressions 46,v andv the meeting edges in the bottoms-of these depressionsA are provided with notches to form elongated slots 47. each slot 47 isja locking pinj48, these pins Extending through VThe upper end of each pin 48 terminates in a transverse head 50 which projects later- .ally away from its opposite sides, and each head is provided in its top surface with a kerf 51, adapted to receive the end of a screw-driver, or similar` tool, for rotatin pins 48 so as'to move heads 50 to stan' either transversely across the edges to lock the plates or parallel with slots 47 to permit the removal of' the plates. Whenr the heads stand transversely across the edges, they retainthe edgesl in contact with each other and effectively prevent the outer edges of the plate members 35, 36, 37, 38., 39 and 40 from slipping out from under the hooks 44. Two pins 48 are used in the heel portion, three in the instep portion and two in the toe portion as will be clear vfrom Figs. I

2 and 3. Only one pin is necessary inthe plate 41 as the'plate is narrow and yis formed of a single piece of metal.

By means of the herein described con-l struction, the plates may be easily unlocked and taken out for theremoval and replacement -of theY spikes or ca lks 31, when the retaining means,"a 'spike-retaining means' adaptedto'be inserted under the preceding' means and resting upon4 the upper ends of the spikes for holdingvthe latter inoperative position, and means for locking said spikeretaining-means in o erative position.
